笔试面试 如下代码的输出是什么?package mainimport (“fmt”)func main() {var nums = make([]int, 0, 4)for i := 1; i <= 4; i++ {Append(nums, i)}fmt.Println(nums)}func Append(nums []int, num int) {nums = append(nums, num)}
笔试面试 如下程序的执行结果为:1 package mainimport (“fmt”)func main( ) {m := make(map[int]*int)s := []int{1,2,3}for _, v := range s {m[v] = &v}fmt.Println(*m[2])}
